Specification of Letters Patent.

Patented Oct. 111, 1913.

Application led April 21, 1910i. Serial No. 556,870.

To all whom t may concern A Be it known that we, VlRGINIA V. BoLL's andEDWIN R. CRooxnR, both citizens of the United States, residing at LosAngeles, in the county of Los Angeles and State 'of California, haveinvented a new and useful Oven, of which the following is a specification.

This invention relates to an oven adapted to be set over a gas stove orother heating means and to be heated by the current of hot air arisingfrom such heating means.v

The main object of the present invention is to provide an oven of thischaracter which can be used for baking, boiling, b'roil' ing and othercooking purposes.

Another object of the invention is to economize as far as possible theheat delivered by the heating means.

A further object of the invention is to provide in an oven of this kinda plurality of compartments and means for separately controlling theheat delivered to the several compartments.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate the invention, and referringthereto: Figure 1 is a front elevation of one form of the oven. Fig. 2is a longitudinal, vertical section thereof.

Referring to Figs. 1 and 2, the oven comprises a casing of sheet metalformed with a back 1, ends 2 and top 3. The bottom of said casing isopen as indicated at 1 and the front thereof has an opening adapted tobe closed by a door 5 hinged, in suitable lugs 8 and provided withfastening means 8', said door being hollow as indicated at 5' to providean air insulation or to receive other suitable heat insulating means. Aninwardly extending flange 6 is provided around the bottom of the casingto brace the same, and a bottom plate 7 extends across the casingsomewhat above the lower edges of the back and end members, this bottomplate 7 being bent down, as indicated at 7 to rest on the bottom flange6. A plate 11 extends from end to end of the casing near the top thereofforming a passage directly beneath the top 3 of the casing, said passagecommunicating at its forward end with a space below the same andcommunicating with the outer air through openings l0 in the top 3 nearthe front of the oven. A flue or vertical tubular member extends withinthe oven adjacent to the back plate 1, 'said flue being open at itsbottom to the space beneath the bottom plate 7 and communicating at itsupper end with the passage between the plate 11 and the to'p 3 of theoven. A plurality of shelves 20, 22 are provided within the 'ovenextendingA between the end walls thereof, kand being provided withperforations 21 for passage of hot air therethrough. Another shelf orpartition 12 extends within the oven from end to end thereofsubstantially dividing the oven space into lower and upper chambers,this shelf being imperforate and extending suiciently close to the doorto effectively retain the heat delivered into the oven. Said shelvesslide on ledges 19 on the ends of the casing, and shelves 12 and 20 areprovided with flanges 24; fitting around the flue 13 when the shelvesare pushed in. The flue 13 is provided with outlets or openings 15extending into the space beneath the imperforate shelf or partition 12and with outlets or openings 16 extending into the space above saidshelf or partition. Valves or dampers 17, 18 controlled respectively byhandles 17', 18 being located above the respective sets of openings 15and 16, so as to cause the hot air rising through the flue 13 to bedeflected more or less into the respective spaces below and above theshelf 12 as may be required. A deflector 14, preferably formed as acurved plate, extends forwardly from the bottom of the flue 13 into thespace beneath the bottom plate 7 to direct the hot gases or air arisingfrom the heating means into said Hue.

In using the device, the lower compartment beneath the partition 12 canbe used substantially independent of the spaces above said shelf, thelower compartment being used, for example, for baking and the uppercompartment for broiling. At the same time the top of the oven can beused for cooking where bottom heat only is required. The plate 11 servesto confine the heat to the top of the oven, when the fiue valve 18 isopen, to enable the top of the oven to be used for boiling, for example,while the inside of the oven is being used for baking. If it is desired,the openings 15 in the flue 13 may be closed by inverting the partit-ion12 so that the flange 24 on the partition l2 covers the openings 15,thereby preventing heat from the ue entering into the space beneath thepartition 12, in which case most of the heat from the lue 13 would passout of the opening 16 in the iue to the space above the partition 12.The opening 16 in the flue 13 may also be closed by inverting the shelf2O so that the flange 24 on the shelf 2O Would cover the opening 16 inthe iue.

What We claim is:

1. An oven comprising a casing, a partition dividing the casing into aplurality of compartments and a flue for the heating agent formed with aplurality of outlets communicating with said compartments, saidpartition being adjustable and carrying means for varying the dischargeof the heating agent through the respective outlets of said flueaccording to the various adjustments of said partition.

2. An oven comprising a casing, a partition dividing the casing into aplurality ot' compartments and a iiue for the heating agent formed witha plurality of outlets communicating with said compartments, saidpartition being adjustable and carrying means for varying the dischargeof the heating agent through the respective out-- lets of said flueaccording to the various adjustments of said partition, and damper meansin said iue above each of said outlets therein.

In testimony whereof, We have hereunto set our hands at Los Angeles,California, this 14th day of April, 1910.
